automatically. controlled float valve: v 19 adapted to be actuated by a float 21- operat ing in a float chamber 22 connected withpipe 23. The washingwater inthe reservoir 7 is heated. to the requiredtemperature by the admission of blow-off steam and To this endI have pro-[ water thereto. vided a. pipe25 communicating with the blow-oil main 9; and-entering thereservoir '7 where vit is preferably equipped with a plurality of perforated distributingbranches.

26 through which blow-01f steam- -and'vvater aredistributed and mingled with-the Washing water. In order'to prevent water hammer these branches are preferably equipped withvcheck valves-27. I v i Y In certain gbo'iler: washing systemsdesigned prior to my present inventionprovir ision hasbeen made'foradmitting Goldwater Goldwater issup'p'lied to, the washing a water reservoir? through a-coldwater pipe 18- connected with 1 any suitable source of; water supply an'dfia predetermined level of water i'sfmaintained' in the reservoir by an "Water when locomotives under pressure.

water will be heated by; blow-01f steam" to the washing water after it is drawn from the washingwvater reservoirtoreduce the temperature of the washing water sufliciently to enable the washout hose to be handled by the Washers-out. My present invention aims to eliminate the tempering down of the washing water by admitting only so much blow-01f steam and water to the-washing water reservoir as is necessary, to ralse the washmgwater to the requ1red washing temperature. I have provided, therefore, in the pipe 25 a thermostatically controlled valve 28"which is controlled from a thermostat 29 disposed within the reservoir 7. When the temperature falls below a predetermined amount the valve 28 will beopened to admit blow-off steam and water: until thewater 1n the wash ng water -reser 1 voir has been raised to the requlred'temperature whereupon the valve 28is automatically closed to prevent further admission of hot blow-ofi products. To'provide for maintaining the temperature of the washing are notbeing blown off and blow-off steam and water are not available I introduce live steam into the washing water reservoir from a pipe 31 connected withtany suitable source of live steam A pipe 32 connected with the pipe 31 and-provided with the branches 33 within the washing water reservoir conv'eys the steam into the reservoir wherein it is mingled with the washing water. A

thermostatically controlled-valve 34 located" in the pipe 31 and controlled by, athermostat 35 situated in the wash ng water res;

ervoir regulates the admission of live steam. Under ordlnary conditions the washing and Wvater admitted through the valve 28, but 111 cases of emergency when blow-off products are not ava1lable,as before mentioned, the valve 34 will open thereby admitting live steam to the washing water until the temperature thereof has been raised the required amount, ency. of the colder Water to seek the lowest level the pump 12 would .ordinarilydraw from the reservoir 7 through the pump intake pipe 36 the colder water from the reservoir. For the purpose of maintaining a uniform temperature of water throughout the reservoir 7 I have pro videda circulat mg pipe 37 connecting the washout mam 13 with the pipe 25 so that'wa ter will be constantly withdrawn from the bottom of the reservoir and returned through the per.- forated branches 26 thereby maintaining a constant circulationanda uniform temperature of the water in the washingwater res ervoir. A scale pocket 38 is preferably connected with the blow-ofl' main '9 to receive boiler scale, sludge and the like, thereby preventing the same from entering the pipe and clogging the valve 28. wLive steam is Owing to the tend supplied to the pumps 12 and 14 through pipes 39 and 41, respectively, in the usual manner.

The filling water reservoir ,3 receives its supply of water from the feed wr'iterheater 42 which"is connected with the reservoir by pipe 43. The feed water heater, as will be observed, is located at the side of the reservoir and near the top and a predetermined level of water in both the heater 42 and the reservoir 8 is maintained by afloat 44 operating in a chamber 45 connected with the feed water heaterpsaid float being adaptedto actuate a valve 46 disposed in the cold water supply pipe 47 A single float valve is thereby utilized to maintain "'apredetermined water level in both the feed waterheaterand in the filling water reservoir. The water delivered to the feed water heater 42 is heated by exhaust steam delivered to the heater through a pipe 48 which receives the exhaust steam from the pumps 12 and 14 and'from the engines in the power-house. The heater 42 isshown as an open heater equipped with vpans or plates 49 by means of which thesteam and has been preliminarily heated in the heater 42-is further heated by blow-off steam which is delivered beneath the surface of the water in the reservoir by a pipe 52 communicating through a short pipe 53 with the blow-oif main 9. Obviously a portion of the steam which is being discharged through the pipe 9 will rise in the pipe 53 and be discharged into the reservoir 8 where itis mingled with the fiilling Water, whereby this water is directly heated by the blow-off steam from the boiler without being contaminated by the mixture of foul blow-oft water there with. The surplus steam from the feed water heater 42 1s also utillzed for heating the feed Water, said steam being conducted through a pipe 54 and'a branch 55 to the pipe 52. A safety valve 5.6 is" preferably provided in the pipe54 above the pipe 55'to permit escapeof excesspressure. Thecheck valve 57- interposed in the pipe 55 prevents backflow of blow-0H steam from the pipe 53 into the feed water-heater, i

For the purpose of maintaining the temperature of the fillingwa'ter in the reservoir 8 I have connected the refilling main 15 with the feed water heaterthrough a circulating pipe 58 sothat a constant "circulation of the also simultaneously admitted tothe filling itis deli'vered to the filling waterreservoinr The water is constantly circulated fromnthe water reservoir, 8.. 3

From the foregoing it will be observed that the filling wateris preliminarily heated by exhaust steam: from the powerboilers in the feed water heater42 from whence filling water reservoir through the,: feed water heater so that is continuously being heated in this heater and returned to the reservoir.

Blow-ofi steam is also utilized forfurther heating the water in the filling water reservoir and, likewise, the surplus steam rising from the feed water heater i l2, this surplus steam and the blo-w-ofi' steam being mingled with the filling water in the reservoir 8 by discharging the steam below the surface of the water. Additional provision is made for'heatingthe refilling water v by live steam which "is admitted through the pipe 60 to the filling watenwhenever the valve 84 is opened. 1 I

Torprevent the collapse of reservoirs 7 and .8 upon the'formation of vacuums thereinvI haveprovided vacuum valves 59 and 61; The filling water reservoir is provided with" the usual overflow pipe 62" equipped with a vent pipe 63 and both of the reservoirs are provided with suitable i sludge valves 64: through which the boilersmaybe drained and cleaned when desired.

It is believed that my invention and many of: its attendant advantages willbe understood from the foregoing without further description. r

It will be obvious, that my inventio n'contemplates mixing blow-oil steam and water with the Water inthe washing Water res er-' volrto heat the same and, at the same time,

, saving a portion of the blow-off water, that )art of the blow-01f steam is conducted to the filling water reservoir for heating the refilling water, that exhaust steam from the power pumps and boilers is utilized for'preliminarily heating the filling water and that the surplus steam is mingled withtheffilling I water in the reservoir 8 and, that provision is also, made for admitting live steam to both the washing Water and refilling Waterreser voirs.

While I have shown and described one referred and ractical embodiment of my invention it Wll be manifest that the mechanical .details of construction are capable of variation within wide limits withoutdeparting from the essence of the invention or sacrificing any of the material advantages thereof.v i
